What are the implications of using PHP to generate images with numbers that are not directly accessible in the source code?

When generating images with numbers that are not directly accessible in the source code, it is important to ensure that the numbers are not easily predictable or accessible by users. One way to address this issue is by using a secure random number generator function in PHP to generate the numbers dynamically each time the image is requested. This will help prevent users from being able to manipulate or guess the numbers in the image. 

<?php
// Generate a random number between 1 and 100
$randomNumber = random_int(1, 100);

// Create an image with the random number
$image = imagecreate(200, 100);
$bgColor = imagecolorallocate($image, 255, 255, 255);
$textColor = imagecolorallocate($image, 0, 0, 0);
imagestring($image, 5, 50, 50, $randomNumber, $textColor);

// Output the image
header('Content-type: image/png');
imagepng($image);
imagedestroy($image);
?>
